Techie Pay!
When I joined up in 80, TG1&2 were paid more. I had no problem with this as it was a personal choice.
Since then times have changed, drastically. Various trades have been judged(rightly or wrongly) to be worthy of a pay increase. There is no such thing as techie pay, but those individuals in TG1&2 have not had their pay reduced.
Why, IMHO, is it that Techies will only be happy when they get paid more than anyone else irrespective of their salary? The highest scoring Trade in the JSJET system was the dental hygienist. There are other TGs who also deserve more but that is purely subjective.
